CASTROVILLE, Texas — A wildfire has burned more 1,000 acres in South Texas, forcing some people to evacuate, destroying three homes and knocking out power to more than 100 others, officials said.

Gov. Greg Abbott during a news conference on Sunday added Medina County to a disaster declaration that includes 14 other Texas counties. In doing so, Abbott issued a proclamation which states that the Medina County wildfire poses an “imminent threat of widespread or severe damage, injury or loss of life or property.”

The proclamation authorizes all available resources of the state government to be of use when needed to deal with the disaster. Previously established statutes or rules that may “delay necessary action in coping with the disaster” will be suspended.

The blaze that’s forced at least 40 households to evacuate is 50% contained as of Monday morning, officials said.  

The fire has not caused any reported injuries or deaths, but officials in the county west of San Antonio warned residents remaining in the area that there was still high risk the flames could spread.

The wildfire began late Friday afternoon and worsened Sunday because of strong winds and low humidity.

More than 200 firefighters are working to combat the blaze and Medina County Judge Chris Schuchart said that they are praying rain.​
